Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing textiles used in athletic and industrial applications often experience issues with loosening, untieing, and inadequate tensile strength, elasticity, and flame resistance, particularly under harsh conditions.
Innovation Solution
A composite textile is developed with a two-yarn structure comprising meta-aramid and polyester fibers, featuring micro-ridges and hooks that enhance friction and grip, ensuring layers remain aligned under tension, and a specific fiber ratio to optimize performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a single-yarn textile is used, then the structure is simple and manufacturing is easy, but the tensile strength and elasticity are insufficient under harsh conditions
Solution Approach 1:
The patent applies composite materials by combining meta-aramid fibers and polyester fibers in a two-yarn composite structure. The meta-aramid fibers provide high tensile strength and heat resistance, while the polyester fibers provide elasticity and comfort. This composite structure resolves the contradiction by achieving superior tensile strength and elasticity without excessive structural complexity, as the two yarns are integrated through weaving or knitting processes.
2Reliability
If the textile lacks friction-enhancing features, then the surface is smooth and comfortable, but the layers slip under tensile force causing loosening
Solution Approach 1:
The patent applies local quality by creating micro-ridges at specific locations on the yarn surfaces. These micro-ridges are localized surface features that provide friction enhancement only where needed for layer alignment, while the rest of the surface remains relatively smooth for comfort. The hooks extending from the yarn surface provide additional localized friction points that prevent slipping under tensile force without making the entire surface rough.
Solution Approach 2:
The patent uses curved surface features including micro-ridges and hooks that extend from the yarn surface. These curved geometric features increase surface area and friction contact between layers, preventing slipping while maintaining overall surface smoothness. The hooks create interlocking curvature that resists tensile forces attempting to separate the layers.
3Strength
If the textile uses only natural fibers, then the material is comfortable and breathable, but the strength and flame resistance are insufficient
Solution Approach 1:
The patent uses composite materials combining meta-aramid fibers (providing high strength and flame resistance) with polyester fibers (providing elasticity and comfort). This composite approach resolves the contradiction by integrating the beneficial properties of different fiber types to achieve both strength/flame resistance and comfort simultaneously.
Solution Approach 2:
The patent applies parameter changes by selecting specific fiber ratios (meta-aramid to polyester) and fiber diameter ranges to optimize the balance between strength, flame resistance, and comfort. By adjusting these parameters, the textile achieves high tensile strength and flame resistance while maintaining breathability and comfort through the polyester component.
4Stability of the object's composition
If the textile lacks elastic recovery, then the structure is stable, but the textile cannot return to original shape after stretching
Solution Approach 1:
The patent uses composite materials where polyester fibers provide elastic recovery while meta-aramid fibers provide structural stability. The polyester component elastically recovers after stretching, while the meta-aramid component maintains shape stability, resolving the contradiction between these two opposing requirements through material composition.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composite textile exhibits excellent untie-resistance, tensile strength, elasticity, and flame resistance, maintaining stability and comfort during use, suitable for athletic and industrial applications.
Implementation Method 1
The first plurality of micro-ridges and the second plurality of micro-ridges interact to generate friction between the first layer and the second layer and limit movement of the first layer and the second layer with respect to one another
Implementation Method 2
The first yarn includes a plurality of hooks each extending from the first surface toward the second surface. The plurality of hooks may attach to the second surface along the longitudinal axis to limit movement of one of the first layer and the second layer with respect to another

AI summary
A composite textile includes a first layer formed from a two-yarn composite that includes a first yarn formed from meta-aramid fibers and a second yarn formed from polyester fibers. The composite textile includes a second layer formed from the two-yarn composite and abutting the first layer along a longitudinal axis. The first yarn has a first surface, the second yarn has a second surface, and the first yarn includes hooks each extending from the first surface toward the second surface. The first layer includes a first plurality of micro-ridges disposed along the first surface and the second layer includes a second plurality of micro-ridges disposed along the second surface. The first and second plurality of micro-ridges interact to generate friction between the first and second layers and limit movement of the first and second layers with respect to one another as the textile extends along the longitudinal axis.
